We are going to use the following theorem to solve the problem we have
The first thing we can say is that the angle of mGFH is equal to:
[tex]m\angle GFH=50[/tex]
Using the theorem shown above we can determine the angle for c
[tex]m\angle GEH=25[/tex]
Arc in part a
[tex]mEG=155[/tex]
Arc in part b
[tex]mEHG=205[/tex]
